Yes you can do headers without a tune, but then your not getting the most out of your mods. You'll also have a check engine light from moving or removing the Cats and that will get old after a while. It shouldnt hurt anything, but the CEL will get old quick.

i installed long tubes and cai with high flow filter without a tune. made a huge difference as far as seat of the pants feel. i don't get on it too hard though until i get it tuned, but the difference really comes in when i throw 5 gallons of MS 109 race fuel...

Headers
My car is all stock except for American Racing mid length headers and high-flow cats and an air box 7 speed manual last week it put down 615 horsepower 640 lb of torque after having the stock exhaust manifolds off and looking at them comparing American mid length headers to them you can see why they flow better plus you save 38 lb off the front
